Senator Nunn appeared on Andrea Mitchell Reports (MSNBC) to discuss a recent open letter sent to Presidents Trump and Putin by himself, Des Browne, Wolfgang Ischinger, and Igor Ivanov ahead of the two leaders' meeting at the July 2017 G20 Summit.

This event--moderated by E.J. Dionne of the Washington Post and featuring Sam Nunn, Bishop Oscar Cantú and Prof. Maryann Cusimano Love--considered the moral and policy implications of major new initiatives by Pope Francis and the Holy See on nuclear proliferation and disarmament.
